Precision Engineering: Manufactured to strict OEM tolerances, guaranteeing reliable performance in CAT U5MK8266 engines.
Optimized Flow Rate: The 297-3050 / 339-3014 oil pump maintains essential pressure and flow for effective engine lubrication under all operating conditions.
Durable Construction: Designed to withstand the high temperatures and continuous operation typical of construction machinery applications.
Accurate Sensing: Komatsu 7861-92-4800 float switch provides accurate, real-time fluid level data, preventing costly damage.
Direct Fit Replacement: Ensures hassle-free installation, making it the ideal OEM Alternative for quick maintenance and repair.
1. Cylinder Liner: Positioned in the Engine Block. Component keyword: Komatsu PC300-8 6D107 Liner Kit. It forms the cylinder wall.
2. Piston: Located in the Cylinder. Component keyword: CAT 320D C6.4 Piston. Converts gas expansion energy into mechanical energy.
3. Crankshaft: Located in the Engine Block. Component keyword: Cummins QSB5.9 Crankshaft. Converts reciprocating motion into rotational motion.
4. Nozzle (Injector): Located in the Cylinder Head/Manifold. Component keyword: Isuzu 4HK1 Nozzle. Sprays fuel into the combustion chamber.
5. Engine Bearing: Supports the Crankshaft/Connecting Rod. Component keyword: Yanmar ViO50 4TNV88 Engine Bearing. Reduces friction between rotating parts.
6. Radiator: Located in the Cooling System. Component keyword: Kubota KX080-3 V3307 Radiator. Dissipates heat from the engine coolant.
7. Pressure Switch: Located in the Engine Oil/Air System. Component keyword: Weichai WP6 Pressure Switch. Monitors system pressure and triggers warnings.
8. Valve Guide: Located in the Cylinder Head. Component keyword: Mitsubishi 6D16 Valve Guide. Guides the movement of the engine valves.
9. Flameout Solenoid: Located in the Fuel System. Component keyword: HINO J05E Flameout Solenoid. Controls the fuel supply to shut down the engine.
10. Monitor: Located in the Operator Cabin. Component keyword: Volvo EC210B D6E Monitor. Displays essential machine operating data.
Failure Symptom: Low or zero oil pressure warning on the dashboard monitor, especially under high load or high temperature conditions, indicating a potential failure of the CAT Oil Pump 297-3050. This can lead to rapid engine wear and catastrophic failure.
Treatment Solution: Immediately shut down the CAT 320D C6.4 engine. Inspect the oil pan for blockages, check the oil strainer, and then replace the old pump with a reliable OEM Alternative oil pump, like the high-quality replacement for 297-3050 / 339-3014. Always refill with the correct grade of engine oil and check pressure before resuming operation.
For optimal performance and longevity of your heavy equipment, implement a comprehensive maintenance schedule. This includes: Regular replacement of Oil Filters and Air Filters; inspection and adjustment of the Valve Guide clearance; checking the condition of Gasket Kits for leaks; and verifying the proper function of all sensors, including the Komatsu 7861-92-4800 Float Switch. Use only high-quality replacement components for critical parts like the Crankshaft and Connecting Rod.
